& MUNITIONSFABRIKEN, OF BERLIN, GER- COLLAR FOR SHAFT-BEARINGS OR THELIKE.

SPECIFICATION forming part of Letters Patent No. 714,611, dated November25, 1902.

- Application filed March 19, 1902. Serial No. 98,980. (No model.)

To ctZZ whom it may concern.-

Be it known that I, AUGUST RIEBE, engineer, a subject of the Emperor ofGermany, residing at Waldenserstrasse, Berlin, in the Empire of Germany,have invented certain new and useful Improvements in or Connected withCollars for Shaft-Bearings or the Like, of which the following is aspecification, reference being had to the drawings hereunto annexed, andto the letters marked thereon.

The invention relates to a check-ring or stop-collar for the bearings ofshafts, axles, spindles, or the like, in which the body of the collar orring is formed by the more or less closely-packed coils of a helicalspring. This mode of construction renders it possible to insert at anydesired part upon a shaft, spindle, or axle a stop-collar surpassing theordinary stop-collars in durability and capable of yielding resistingshocks. The introduction of the helical spring into the annular recessforming its seat is effected by passing the spring through an obliqueslot or groove formed in the fixed collar, which constitutes one side ofthe annular recess which serves as the seat of the spring-collar.

In the accompanying drawings, Figure 1 represents a side elevation ofpart of a shaft or spindle on which a helical-spring collar constructedaccording to the present invention is shown in section, holding in placeupon the shaft or spindlea ball-bearing, which is likewise shown insection; and Fig. 2 illustrates the mode of introducingthe helicalspring into its seat.

In both figures of the drawings like parts are indicated by similarletters of reference.

The shaft or is provided contiguous to the point where the spring-collaris to be inserted with a shoulder or'fixed collar b, forming one side ofan annular recess 0, while the opposite side is formed, according to themethod of construction shown in the drawings, by the collar d, whichcarries a ball-bearing 6, provided with inner and outer ball races orbushes and which abuts against the fixed flange or shoulder g. Thehelical collar in this instance is intended to serve the purpose ofkeeping the ball-bearing e in position. A helical spring f, made of fiatsteel, is used for forming the helical-spring collar, which is introduced into its seat by passing it, in the manner shown in Fig. 2, throughan oblique slot or groove 3 in the fixed collar or shoulder 12,

arranged so as to correspond in shape and pitch to a portion of thehelical spring, and

the spring is forced by a kind of screwingv motion into the annularrecess 0 until all its coils are compressed into said annular recess,thus forming the compact resilient springcollar shown in Fig. 1.

It is expedient to smooth or polish in a suitable manner the end or sidefaces of the helical spring, after having adj ustedit to a properlength, before introducing it into the recess, so that they may offer aminimum of frictional resistance during said fitting operation.

The outer periphery of the helical spring may be roughened or notchedfor the purpose of facilitating the application of a tool in order toforce the spring through the slot 3. After the end of the coil has beenbrought into the recess cthe spring-collar thus formed may slide withinthe recess without any possibility of its becoming dislodged from itsposition.

Having now particularly described and ascertained the nature of the saidinvention and in What manner the same is to be performed, I declare thatwhat I claim is- 1. In a device of the character described, thecombination with a shaft having a relatively constricted portion, and acollar to be secured in place thereon, of a helical spring adapted to becompressed between the collar and the shoulder formed by the side of theconstricted portion and an opening extending transversely through theshoulder and adapted to receive the spring.

2. In a device of the character described, the combination with a shaft,two enlargements thereon, and a collar to be secured in place betweensaid enlargements, of a helical spring adapted to be interposed betweenone of the enlargements and the collar, there being a channel formed inone of the enlargements to permit the passage of the springtherethrough.

3. In a device of the character described, the combination with a shaft,a fixed support thereon, a second fixed support having a slottherethrough, and a collar to be secured in place between the two fixedsupports, of a helical spring adapted to be passed through the slot andcompressed between the collar and one of the fixed supports.

4. In a device of the character described, the combination with a shaft,a fixed support thereon, a second fixed support having an oblique slottherethrough, and a collar to be secured in place between the two fixedsupports, of a helical spring adapted to be passed through the obliqueslot and compressed between the collar and one of the fixed supports.

5. In a device of the character described,

the combination with a shaft, a relative enlargement thereon, a secondrelative enlargebearing-collar firmly against the other enlargement.
